5. lenora is mulching her flower garden.
she was able to mulch 48 square feet of
garden before lunch. she plans to finish
the job after lunch. each bag of mulch
covers 24 square feet of garden.
a. write an equation that represents the
number of square feet of garden given
a certain number of bags of mulch.
b. graph the equation.
c. identify the slope and y-intercept of
the graph. explain what each means in
terms of the situation.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
